SULPHUR FABRlC.

SPECIFICATION forming part of Letters Patent No. 407,311, dated July 16,1889.

Application filed March 5, 1889. Serial No. 302,012. (Speoimensd To allwhom it may concern.-

Be it known that I, HENRY PH. .WEIDIG, a citizen of the German Empire,and a resident of Newark, in the county of Essex and State of NewJersey, have invented anew and usef ul Improvement in Sulphur Fabrics,of which.

the following is a specification.

The object of my invention is to produce fabrics-such as paper, linen,or cotton cloththoroughly impregnated with sulphur, in a condition whichwill insure the greatest possible pliability of the product and firmlysecure the sulphur to the fabric.

Paper and cloth have prior to my invention been coated with sulphur bydipping narrow strips into molten sulphur. By this method stiff andbrittle strips are produced, the sulphur forming an unbroken crustcovering the surface of the paper or cloth.

Instead of dipping the paper or cloth into molten sulphur, I prepare asolution of sulphur in a volatile solvent, (by preference bisulphide ofcarbon), draw sheets of paper or cloth through the solution, and allowthe solvent to evaporate, repeating the operation as often as necessaryfor the desired saturation of the fabric. Instead of being coated Thesulphur sheets produced by this method, owing to the granular orcrystalline structure of 'the deposit, retain a high degree ofpliability, and even when creased the sulphur does not splinter as itdoes in ordinary sulphur strips, such as are in the market and used forsulphuring wine-casks, (to. These sheets of paper or cloth, impregnatedwith granular or crystalline surphur, form a suitable material for agreat variety of purposes. They may, for instance, be used for wrappingfurs and woolen goods, to prevent their destructionby insects, or theymay be placed underneath wall-paper and carpets, to prevent dampness andmold.

Strips of the fabric may be burned for disinfecting houses withoutdanger from (ii-Q)- ping sulphur, as in the case of ordinary sul-- phurstrips.

WVhat I claim as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, a fabric consisting of paper or textilematerial impregnated with granular or crystalline sulphur, substantiallyas set forth.

In testimony that I claim the foregoing as my inventionI have signed myname, in presence of two witnesses, this the 1st day of March, 1889.
